From 64dd2ee656bb0005524d781c28e4c227d6bc5a22 Mon Sep 17 00:00:00 2001
From: ru <ru@FreeBSD.org>
Date: Thu, 17 Oct 2002 13:48:13 +0000
Subject: Added the new variable CTAGS which, if set to "ctags", reverts to
 creating the tags file using ctags(1).  Defaults to "gtags". Made GTAGSFLAGS
 and HTAGSFLAGS overrideable, added CTAGSFLAGS. Folded bsd.prog.mk version of
 `tags' into bsd.dep.mk.
